165 heater is making alot of smoke

I have been using my heater for 2 weeks and it is only on the second tankful of fuel. It is producing a lot of smoke when it is running, which it did not do on the first tank of fuel. I am using #2 diesel fuel.

Smoke is an indication of an improper air/fuel mixture, partially blocked nozzle or blocked air passages.

Kerosene must be atomized and mixed with the right amount of air to burn without smoke and odor.
You should consult your manual to have a guide to resolving the issue.
1. Make sure pump pressure is set accurate (5.6 p.s.i.). The pump controls the air/fuel mixture.
2. remove nozzle and clean with brush and compressed air. Also inspect rear of combustion chamber where air flows into and around the chamber to ensure proper air flow. Any materials that may be bent should be replaced. If not formed properly, the air flow through the heater changes as a result.

    diesel will make a noticeable change vs. kerosene, but should not produce smoke unless the fuel is contaminated. Remove the fuel pick-up tube from the tank, place into a clean one quart far of k1 kerosene sitting next to the tank. see if the burn is cleaner with new fuel

When the heater is turned up to a higher btu , it cuts off after a short time


What size tank? when it's really cold a small tank will not produce enough vapor fast enough. It could be a weak valve in the tank snap'n shut If the fuel comes out to fast. Could also be high temp switch on back of burner going bad. That happens alot.

After plugging in the blower comes on for about five seconds and then there a small puff of smoke and it shuts off. any answers? thanks


Hick, check your fuel tank for trash & water. Use a flash light and look inside. You can drain it at the bottom of the tank (plug). Most of the time water is picked up if your tank has not been cleaned before. Moisture accumilates in the tank during the warm/hot months of the season. If tank has water or trash, drain and dispose fuel properly and check your fuel filter. Replace if neccessary. Add fresh fuel and test again. Check this before you go any further with troubleshooting.

Sounds like there might be some water in the fuel?
Take a strong flashlight, and shine it into the tank-- does it look dirty?-- can you see water on the bottom? Try draining and cleaning the tank, and make sure the suction filter is clean-- and in tact.
And yo are using kerosene-- not diesel fuel, right?

100,000 btu reddy heater runs but smokes alot and you can smell raw fuel what's wrong


It sounds like the fuel is contaminated,if it is not k 1 kerosene ,or grade A diesel fuel,this could be the problem,clean the tank,and start with a k 1 kerosene,and see if it clears up,then go back to the grade A diesel fuel,if this does not work,replace the filter in the tank,and check the intake air filter,make sure it is not cloded up,or behind the filter,last thing ,only after checking and doing all of this,the pump pressure may need adjusting,but do not try this with out a pressure gauge,and a manual .You can break the pump easy.I have a manual for the ready heater,just let me no if you need it,please rate,thank yopu,> roniecon@gmail.com

I have a 55,000 BTU Reddy Heater that runs on K-1 Kerosene. I used it several weeks ago and it seemed to stik far more than usual. I tried to used it yesterday and now it seems to come on for a second...


Water in the fuel tank, I personally had this problem this morning irritating but was simple to cure. Empty your fuel in to a clean five gallon bucket and observe, fuel is lighter than water and will float on top water settles to the bottom. You now have to dry out the tank, get creative I stuffed mine with rags and sopped it all up, this worked fine for me. You can siphon off the fuel from the water and re-use the fuel. Just be careful not to siphon off the water with it.

I have a master 150000 btu kerosene direct fire heater that runs for 5 minutes then shuts down and blows white smoke. what is the problem?


The white smoke is the kerosene fuel hitting the hot combustion chamber. Your flame has went out. The cause for this could be many. The first thing you need to do is check your fuel. Remove your fuel cap and look at the bottom of the tank for trash or water. Use a good flash light. It will all settle to the bottom. If so, drain and clean out your tank. Add fresh kerosene. Check your fuel filter. Replace if dirty. Test again. If problem continues, It is possible that your photo eye could be deffective or just dirty. It is located next to the ignitor or spark plug. It sees the flame. If the flame goes out, the unit shuts down. The flame has to be smooth (not sputtering). Water in the fuel will make it sputter and the unit will shut down. When the water/moisture in tank settles to the bottom, your suction fuel line is just off the bottom which results in it picking up the water instead of good fuel. Always disgard the old fuel from previous year and start with fresh fuel. This will cut down alot of your problems in the future.

THE HEATER STARTS THEB BLOWS ALOT OF SMOKE


There are any number possibilities for intermittent running.
1. Bad ground connection at the Ignition Device (transformer, spark box)
2. restricted fuel filter causing fuel starvation
3. crack in the plastic end cover
4. crack in the airline
5. crack in the fuel line
6. crack in the nozzle adapter
7. water in the fuel
8. Others I’m sure I left out

You must be the one to troubleshoot & find the cause.

Clicks but wont fire


make sure the high voltage lead to the sparkplug isn't touching anything metal on its way to the plug. the clicking may be the high voltage discharging to a metal part, not the plug. those wires age during use.
